5. General Relativity Simulation Contest
The purpose of this Contest is to prove General relativity using a (simple) algorithm.
General Relativity Simulation Contest
Description of Contest
The purpose of this Contest is to prove General Relativity.
The Contest consist of the following task:
  • Write one general purpose program (any programming language will do) which simulates the movement of n objects over a certain period of time.
  • The simulation method used (algorithms), should be based on the Rules of General Relativity.
  • The program should be able to simulate and demonstrate the following examples:
  • Forward movement (perihelion shift) of the planet Mercury (43 arc sec angle) around the Sun.
  • The bending of light around the Sun (1.75 sec).
  • The movement of a binary star system. The stars should spiral together.
  • A clock in a space ship around the Earth.
  • Twin paradox (SR). i.e. at least two clocks should be included.
  • The behaviour of black holes.
  • The results of the simulation should match actual observations. For the rules of General Relativity see the following: General Relativity with John Baez
    For the most elaborate list of links for General Relativity see: Relativity on the World Wide Web by Chris Hillman , maintained by John Baez

    Relativity Tutorial
    Galilean Relativity
    Relativity can be described using space-time diagrams . Contrary to popular opinion, Einstein did not invent relativity. Galileo preceded him. Aristotle had proposed that moving objects (on the Earth) had a natural tendency to slow down and stop. This is shown in the space-time diagram below.
    Note the curved worldline above. This shows a variable velocity, or an acceleration . Galileo objected to Aristotle's hypothesis, and asked what happened to an object moving on a moving ship.
    Now it is still moving in its final state. Galileo proposed that it is only relative velocities that matter. Thus a space-time diagram can be transformed by painting it on the side of a deck of cards, and then skewing the deck to one side but keeping the edges along a straight line:
    Straight worldlines (unaccelerated particles) remain straight in this process. Thus Newton's First Law is preserved, and non-accelerated worldlines are special. This Galilean transformation does not affect the time. Thus two observers moving with respect to each other can still agree on the time, and thus the distance between two objects, which is the difference in their positions measured at equal times, can be defined. This allowed Newton to describe an inverse square law for gravity. But Galilean transformations do not preserve velocity. Thus the statement "The speed limit is 70 mph" does not make sense but don't try this in court. According to relativity, this must be re-expressed as "The magnitude of the relative velocity between your car and the pavement must be less than 70 mph". Relative velocities are OK.

    9. Relativity
    Provides information on the history, experiments and paradoxes of relativity.
    The theory of special relativity (or special relativity for short) was established in 1905 by the famous physicist Albert Einstein at the age of 26. Special relativity is of importance in the realm of high relative velocities. It has been thoroughly verified on numerous occasions and has always stood up to the critical tests. Special relativity is now a tool at work, almost daily, in the scientists' calculations and laboratories. For users: 18 +

    Some examples of the phenomena of general relativity are simulated. This provides a graphical sight on the main general relativity concepts. The simulations include solutions in 3D (XY +time) and 4D (XYZ+time) spaces.
    ABSTRACT Some examples of the phenomena of general relativity are simulated. This provides a graphical and quite illustrative sight on the main general relativity concepts. The simulations include solutions in 3D (XY +time) and 4D (XYZ+time) spaces. The solutions are more general than those which can be obtained analytically. For example, the approach to the black hole is simulated not only as a radial particle movement, but as an arbitrary trajectory in the 3D space. The distortion of images of far objects seen through a neighborhood of a black hole is simulated using photon trajectories in 4D space. Also the entrance of an arbitrary trajectory into the horizon of the black hole is simulated both with the coordinate time (seen by the static observer) and with the proper time (clock) of the moving body. Time distortion at the neighborhood of the black hole is shown as a 3D “space-distortion” plot. Interesting simulation experiments are also shown for the rotating black hole.

    Major advances in computation are only now enabling scientists to simulate how black holes form, evolve, and interact. Learn about relativity and its predictions through text and video files at this site.
    In 1905, Albert Einstein published his famous Special Theory of Relativity and overthrew commonsense assumptions about space and time. Relative to the observer, both are altered near the speed of light: distances appear to stretch; clocks tick more slowly. A decade and a year later, Einstein further challenged conventional wisdom by describing gravity as the warping of spacetime, not a force acting at a distance. Since then, Einstein's revolutionary insights have largely stood the test of time. One by one, his predictions have been borne out by experiment and observation. But it wasn't until much later that scientists accepted one of the most dramatic ramifications of Einstein's theory of gravitation: the existence of black holes from whose extreme gravity nothing, not even light, can escape. Major advances in computation are only now enabling scientists to simulate how black holes form, evolve, and interact. They're betting on powerful instruments now under construction to confirm that these exotic objects actually exist. You might like to take a two-minute video tour of this exhibit's contents.

    It's in the stars
    One of the most challenging problems in modern physics is the application of quantum theory to the universe as a whole. Progress in this area has been plagued by two types of problem: conceptual and technical. The conceptual problems arise from the old difficulties of interpreting quantum theory. The standard interpretations require that the measuring instruments and observers are outside the quantum system described by the wavefunction. In the late 1950s, however, Hugh Everett proposed an interpretation of quantum theory that might apply to systems that include the observers and measuring instruments, but the adequacy of such interpretations has remained controversial to this day. The technical problems are no less severe or fundamental. Ever since the pioneering work of Bryce DeWitt, Charles Misner and others in the 1960s, quantum cosmology has basically been studied by applying quantum theory to simple models of the universe. These models typically assume that the universe is completely homogeneous. As a result they only have a few degrees of freedom - the radius of the universe and the value of one or more matter fields. One then makes a quantum-cosmological model by quantizing these simple descriptions of the universe.
